FEATURES:
The 2M5WL is designed with the SERIOUS "Weak Signal" enthusiast in mind. It provides excellent gain for min-
imum weight and wind load yet is strong enough to survive 100+ mph winds. The modified folded dipole driven element is
also unique as it's center is a CNC machined block of aluminum fitted with 'O' ringed connectors and access cap. After
factory assembly, the block is filled with a space age silicone gel which further seals and increases dielectric breakdown
and arc-over protection. The 3/16" rod elements mount through the boom on UV stabilized button insulators. All hardware
is stainless steel except for U-bolts. A vertical riser and an overhead Dacron cord guy system is supplied for boom sup-
port. This antenna is widely used in EME (W5UN's 48 2M5WL's and many others) and large Tropo scatter arrays. Sever-
al optional items are available to provide more gain from your 2M5WL's. 2 and 4 port power dividers are available for
matching stacks of 2 or 4 antennas. 50 Ohm phasing lines model VHF-50-2M5WL2 and VHF-50-2M5WL4 can be ordered
for phasing 2 or 4 antennas together. 'H' frames, OR-2800 and MT-3000 AZ and EL rotators are also available as well as
Rohn and US towers.
